The perimeter of the semicircle is 19π cm if the diameter of the circle is 38 cm.
<h3>What is a circle?</h3>
It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)
We have a circle with diameter of 38 cm.
Diameter = 38 cm
The radius of the circle = 38/2 = 19 cm
Perimeter of the circle = 2πr = 2π(19) = 38π cm
Perimeter of the semicircle = 38π/2 = 19π cm
Thus, the perimeter of the semicircle is 19π cm if the diameter of the circle is 38 cm.

This is a right triangle and you can use the Pythagorean theorem to find the missing side.
5^2 + 12^2 = c^2
25 + 144 = c^2
169 = c^2
square root of 169 = c
13.
So the missing side is 13m
